TL;DR

- Quantum computing is a computational paradigm that exploits quantum-mechanical phenomena—superposition, entanglement, and interference—to process information using qubits rather than classical bits.
- What is the difference between a qubit and a classical bit?
- What is India's National Quantum Mission and when was it launched?
- Why does quantum computing threaten current cryptography?
- What does the term NISQ mean?

Example

In April 2023, India's Union Cabinet approved the National Quantum Mission with a ₹6,003.65 crore outlay, aiming to build 50–1000 qubit quantum computers and four thematic hubs by 2031 under the Department of Science and Technology.
